A rapid method for making skull patch for anatomical reconstruction

Abstract

The invention discloses an anatomy reconstruction skull patch filling a skull defect opening part. An edge shape of the patch is identical to an edge shape of the skull defect opening; a patch stereoscopic structure is identical to a skull defect stereoscopic structure; and the patch is made of degradable biological hard material. The invention further discloses an anatomy reconstruction skull patch quick manufacturing method. The patch manufacturing method can produce patches with high accuracy, great coupling property, great repairing exactness, firmness and safety as well as reliability; great patch structure and biocompatibility can be achieved; surgery cost can be reduced and time can be shortened; and post-surgery complications can be reduced.

Description

technical field [0001] The invention relates to a medical device, in particular to an anatomical reconstruction bone patch and a rapid manufacturing method thereof. Background technique [0002] Intracranial tumors, also known as brain tumors, refer to nervous system tumors that occur in the cranial cavity, including tumors originating from neuroepithelium, peripheral nerves, meninges and germ cells, lymphoid and hematopoietic tissue tumors, and craniopharyngiomas in the sella region and granulosa cell tumors, as well as metastatic tumors. Intracranial tumors bring huge health hazards, mental pressure, and economic burden to patients and their families, and seriously affect the quality of life of patients. At present, surgery is mainly used to treat intracranial tumors clinically, but whether it is conventional surgery or minimally invasive surgery such as endoscopic microscope, in the process of opening the skull, it will cause bone defect damage at the surgical approach s...

AI Technical Summary

Problems solved by technology

At present, surgery is mainly used to treat intracranial tumors, but whether it is conventional surgery or minimally invasive surgery such as endoscopic microscope, in the process of opening the skull, it will cause bone defect damage at the surgical approach site

[0003] The existing surgical repair methods usually have rough manufacturing and repair methods. After repair, the extracranial side is relatively flat, but the intracranial side is quite different from the original structure, which may lead to brain damage beyond surgery.

Some existing repair methods are difficult to repair successfully in one operation, and need additional attempts to repair successfully, which undoubtedly prolongs the operation time and increases the risk of operation

In addition, the physical properties of materials, including thermal conductivity, electrical conductivity, magnetism, ductility, etc., may bring troubles to the subsequent treatment of diseases

The materials currently used are all expensive and difficult to form, let alone restore the anatomical structure of the surgical site to achieve the purpose of rapid anatomical reconstruction

If autologous tissue is used for repair, additional trauma is required and the risk of postoperative complications is further increased
